| 摘 要： | 讨论了一种基于数学形态学的心电图波形分离方法。使用这种方法，无须检测QRS波群，利用一系列形态学运算，便可以直接去除心电信号中的QRS波群，检出P波和T波的起止点，实现波形的定性和定量分离。定性分离效果甚佳，定量分离结果的方差较小。此外，心电信号的滤波、基线矫正等处理，也完全由类似的形态学算法实现。

| Abstract: | An ECG waves separation technique based on mathematical morphology is suggested and discussed in this paper. Without detection of QRS complexes, the QRS complexes can be eliminated by series morphological operations. Then the start points and end points of P wave and T wave can be decided and the waves of ECG are separated qualitatively and quantitatively. The results of qualitative separations are rather satisfied and the SDs of quantitative separation results are not very large. Also, ECG signals are filtered and baseline is normalized by morphological method. |
